SQuaScheD - Unsupervised Schema Discovery for Heterogeneous Data

We provide on this web site additional material related to the article "Here is the Data. Where is its Schema?" submitted to the 24^th International WWW Conference 2015 as submission #312.

You will find below the detailed hierarchies, ground truth class distributions and MDL evolution for hierarchies discovered by SQuaScheD on all datasets mentioned in the paper.

Detailed SQuaScheD Discovered Hierarchies

We present below interactive visualizations showing the most representative attributes and entities for each class of the SQuaScheD discovered hierarchies for each datasets:

• Activity-EducationalInstitution
• ArchitecturalStructure
• Event-NaturalPlace-WrittenWork
• Event
• Infrastructure
• RouteOfTransportation
• Species
• Tunnel

Ground Truth Class Distribution

Distribution of the bottom-most ground-truth class in the discovered class hierarchy for all datasets.

MDL Evolution in SQuaScheD

The figures below show the evolution of the MDL, class-precision, -recall, and -F2 along the steps of the SQUASCHED process for all datasets.
